Natural Language Processing (NLP) is a field of artificial intelligence that gives machines the ability to read, understand, and derive meaning from human languages. NLP involves the interaction between computers and human language, enabling tasks such as text analysis, translation, sentiment analysis, and speech recognition. Techniques used in NLP include tokenization, part-of-speech tagging, named entity recognition, and syntactic parsing. By leveraging machine learning and linguistic rules, NLP systems can analyze and interpret large volumes of unstructured text data, facilitating applications like chatbots, language translation services, and automated content generation.
